[Veritas-bu] Raid5 or mirrored?

Performance used to dictate that a mirrorred set was faster. However if you
are running with any of the newer raid controllers the difference is
negligable.

Subject: [Veritas-bu] Raid5 or mirrored?
I'm setting up a file system for /usr/openv using volume manager with
four disks, and I'm wondering if it would be better to make it a raid5
system, or a concatenated mirror. If I use mirroring, then my disk
space is limited to that of the two disks, but with raid5, I get an
extra disk space. For performance reasons, what would be the best
layout of disks?
thanks
robert
